BALL-BEARING.

SPECIFICATION forming part of Letters Patent N. 651,376, dated rune 12,1900. Application tiled January 26, 190. Serial No. 2,926. (No model.)

To @ZZ whom t may concern.-

Beit known that we, OSGOOD MORRILL, a citizen of the United States, andHABLAN P. WELLS, a subject of the Queen of Great Britain and Ireland,residing at Amesbury, in the county of Essex and State of Massachusetts,have invented certain new and useful Improvements in Ball-Bearings, ofwhich the following is a specification.

The object of our invention is the produc-'- tion of a ball-bearingwhich shall be comparatively simple in construction and not liable tobecome deranged or inoperative; which will wear evenly; which shall havethe balls confined or held in combination with rings or between them insuch a way as to form a cage,

so that the balls and rings can be adjusted and removed together withoutthe separation of the rings and the displacement of the balls; 'whichshall admit of the adjustment of the rings relative to the balls for thepurpose of compensating for wear; which shall have the parts so arrangedand tted one to another that dust and other foreign substances will beexcluded from contact with the wearing surfaces, and which shall possessother desirable features and characteristics constituting it a superiordevice for performing the required functions.

With the above end in view our invention consists, objectively, in aball-bearing comprising an axle or shaft, two cages embracing rings andballs, a hub or box having seats for the cages, and means for excludingdus-t and dirt.

It further consists in a cage for ball-bearings, said cage comprising anauxiliary casing within which is contained balls and rings in contactwith the balls.

It further consists in a cage for ball-bearings, said cage comprising anauxiliary casing, two beveled rings, and a cylindrical ring, the ringsand balls so held by the casing that the cage can be adjusted inoperative position and removed without liability of the parts becomingdisarranged or separated.

Finally, it consists in certain novelties of construction andcombinations and arrangements of parts hereinafter set forth andclaimed.

The accompanying drawings illustrate an example of the physicalembodiment of our invention embracing two cages and their application toa vehicle-axle constructed and arranged according to the best of theseveral modes we have so far devised for the application of theprinciple.

Figure l is a view, partly in section, of the said example, showing avehicle-axle, an axlebox, 'and two ball-bearing cages in positionwithinthe box and engaging the axle. Fig. 2 is a perspective view of aball-bearing cage. Fig. 3v is a plan view of the rear threaded washer.Fig. 4 is a plan View of the front threaded washer. Fig. 5 is aperspective View of one of the beveled rings removed from the casing.

Referring to the several'figures, the letter A designates an axle,shaft, or spindle.

B is a collar on the axle, said collar being provided with a circularflange extending parallel with the axle.

C is the end of the axle, somewhat reduced in diameter.

D is a shoulder.

E is the threaded end of the axle.

F is a threaded nut.

G designates an axle-box of any suitable construction. l

H H are enlarged portions of the box at the ends thereof forming seats.

I I are internal screw-threads.

J is a threaded washer adapted to engage the threads l.

K is a circular groove in the face of the washer adapted to receive theflange of' the collar B on the axle.

Lis the threaded washer, adapted to engage the threads I at the frontend of the box.

M are notches or recesses in the rear andA front washers adapted toreceive a wrench.

N is an externally-threaded cap adapted to engage the threads I at thefront end of the box.

O O are ball-bearing cages.

P P are beveled rings.

Q is a grooved cylindrical ring.

R are the balls.

S S designate the auxiliary metallic casings which receive the beveledrings and balls and hold them in combination with the cylin drical ringsQ, as shown in Fig. 1.

IOO

T T are the circular edges of the casings, and U designates` thebeveled'edge of the washer J, located at theinner end of the box.

lt will be observed that each cage comprises, in addition to the seriesof balls, four partsthe cylindrical ring, two beveled rings, and thecasing. The cylindrical ring is grooved to receive the balls. Thebeveled rings frictionally engage the inner surface of the casingsufficiently to prevent their displacement in ordinary handling, and thecasing has one end turned or spun inwardly to a distance about equal tothe thickness of a beveled ring, so as to leave an opening slightlylarger than the diameter of the cylindrical ring. When the parts areassembled, the cage appears as in Fig. 2.

4To assemble the parts of the complete ballbearing, the cages are firstadjusted to their seats within the enlarged ends H l-l of the box. Thewashers J and L are :next screwed tight against the cages by means of awrench which tits the notches M. The axle is then passed through thecylindrical rings Q, and finally the nut F and cap N are applied. Asshown by the drawings, Fig. l, the nut con tacts with the end of' thecylindrical ring Q and t'orces it against the shoulder D, so it cannotturn about the axle. By lengthening the reduced part of the axle C thering Q, may be allowed to turn about the axle. At the outer end of theaxle or box the washer L is in contact with the edge 'l of the casing S.Should the rings or balls become worn, the cago can be removed and theedge T filed away slightly, which will allow the washer when applied tobe screwed farther into the box, and thus take up the wear of the parts.'lo attain the same end, the washer may be beveled, as at U, whichallows it to be advanced into the box and its edge not come in contactwith the edge T of the casing.

From thevforegoing it is obvious that we have produced a ball-bearingwhich fulfils all the conditions set forth as the object or purpose ofour invention. D ust and foreign substances are effectively excluded bymeans of the collar B, having a flange which fits the groove K in thewasher J at the rear and the cap N at the front. Each cage can easily beplaced in position and removed andhandled withoutthe parts becomingseparated and the wear of the parts taken up by means ot' the washers Jand L.

While we have illustrated and described only one complete example of thephysical embodiment of our invention and one specific construction ofthe cage, and that example embracing a vehicle axle and hub, we do notthereby intend to limit the scope thereof to such example. We may embodythe invention in a combination in which the box is stationary and theaxle or spindle or shaft turns or revolves. Changes in construction maylikewise be introduced. The box and its central passage may be ol' thesame diameter from end to end and means provided to serve as seats forthe cages. In certain cases the collar B and the capN maybe omitted. Thecages may be held in their seats by positive means, such as a screw, andthe beveled rings `may be confined in the cages by other means than thefrictional engagement with the casing. We also contemplate the use ot'the cages in other analogous combinations and sometimes propose to use asingle cage at the end of the axle to serve as a tlnust-bearing,especially where the weight of the load is to be taken directly by theaxle or spindle A oli' a vehicle. These and other modifications andspecic applications of the cage or cages we intend to include within thescope of our invention. y

What we claim as new, and desire to secure by Letters Patent, is-

1. A ball-bearing cage comprising an auxiliary cylindrical casing; twobeveled rings frictionally held within the casing and out of con tacteach with the other; a grooved cylindrical ring; and a series of ballsin contact with the groove of the cylindrical ring and the beveledsurfaces of the beveled rings; the ring and balls being held within theauxiliary casing so that the cage can be removed from the bearing andhandled without the liability of displacing the elem ents held by thecasing.

2. A ball-bearing cagecomprising an auxiliary casing, S, having one endturned inwardly; two beveled rings, P P; a grooved cylindrical ring, Q;and a series oli' balls, R; the said rings, P P', being held within thecasin g by the frictional contact of their outer circumferentialsurfaces with the inner surface of the casing.

3. The combination in a ball-bearing of a box having two seats, one ateach end; two ball-bearing cages, each cage embracing an auxiliarycasing, two beveled rings, a cylindrical ring, and balls, and a cagelocated in each seat; means for holding the cages in the seats; an axleor spindle; and means for retaining the axle within the box.

4. The combination in a ball-bearing, of a box having two seats; twocages, each cage comprising an auxiliary casing, two beveled rings, acylindrical ring, and balls; an axle or spindle; a nut; and two washers,one fitting within each seat and against a cage and holding the same ina fixed position Within the box.
